IRRIGATION-VALVE.

Specification of Letters Fatent.

Patented Dec. 6,1921.

Application filed December 4, 1919. Serial No. 342,339.

To all whom it may concern:

Be it known that I, CLINTON J. Konrz. a citizen of the United States,residing at San Diego, in the county of San Diego and State ofCalifornia, have imzented certain new and useful Improvements inIrrigation- Valves, of which the following is specification.

My invention relates to valves to be used in connection with irrigationsystems and the objects of my invention are: first, to provide a novellyconstructed valve for opening and closing the water outlet in irrigationpipe line systems more particularly those of concrete; second, theprovide a valve structure of this class the seat of which is formed ofthe concrete material of which the pipe is made and formed by pressurecontact with the metal valve member; third, to provide a valve structureof this class which is readily made applicable to the different formsand shapes of water outlets as desired and fourth, to provide a valvestructure of this class which is very simple and economical ofconstruction, durable, easy to install, easy to operate and which willnot readily deteriorate or get out of order.

lVith these and other objects in view as will appear hereinafter myinvention consists of certain novel features of construction,combination and arrangement of parts and portions as will be hereinafterdescribed in detail. and particularly set forth in the appended claims,reference being had to the accompanying drawings and to the charactersof reference thereon which form a part of this application, in which:

Figure 1 is a sectional view of my irrigation valve shown in position inconnection with a concrete pipe and showing the valve closed; Fig. 2 isa side elevational view of the upper end thereof showing the valve open;Fig. 3 is a sectional view through 3-3 of Fig. 1; Fig. 4 is a sectionalview showing the application of my valve for use in connection with ametal pipe conductor for conducting the water in laterals from the mainline and showing a slightly modified form of support for the valve seatfor the outer valve and Fig. 5 is a sectional view through 55 of Fig. 4.

Similar characters of reference refer to similar parts and portionsthroughout the several views of the drawings.

The concrete pipe member 1, valve member 2, bolt 3, supporting bars 4and nut 5 constitute theprincipal parts and portions of my valvestructure in its preferred form.

In constructing the concrete pipe member 1, it is formed in theconventional manner and mounted therein in position are the transversebars 4 so that when the concrete hardens the bars are supported rigidlytherein some distance below the top. Mounted between these bars lie thenut 5 whlch 1s provided with a thread adapted for the bolt 3. It isprovided with two grooves.

5 in oppositely disposed sides in which rest the bolts o which perform.the functions of supporting the nut 5 in position and holding the bars tin relative position to each other. It will be noted that the nut 5 ismounted loosely in its position in the center between the two bars sothat it will readily conform to the screw thread and take the bolt 8.The valve member 2 is pireferablya disk plate with a central holeadapted for the'bolt 3 with a gasket washer 3 to form a tight fitbetween the bolt and the member 2. v The outer edge of this member isprovided on the one side with double flanges 2 and 2 and they are placedin position on the top edge of the pipe as shown best in Fig. l of thedrawings and the bolt 3 turned into the nut 5 causing the member 2 tofit tightly and securely on the upper edge of the concrete pipe 1 whileit is green and left to set in this position, after which the bolt 3 isloosened and a gasket 2 secured to the member 2 in the groove betweenthe flanges :2 and 2 and adapted to seat on the seat portion of the pipeformed by the pressure of the members. In case it is desired to uselaterals in connection with the pipe in addition to the structure asjust described there is added an additional flange 1 to the con crete oflarger diameter beveled at 1 and against this beveled portion is mountedan annular member 6 provided with outwardly extending lugs 6 in whichare pivotally mounted bolts 7, annular member 8 provided withclownwardly extending flange portions 8 similar to the flanges 9 and 2on the member 2, and with a plurality of bifurcated lugs 8 adapted forthe bolts 7, and this flange mem ber is screwed down in position on theupper ends of the flange 1 on the green cement on the top edge andpermitted to set, after which it is removed and a gasket 8 placed inposition. On the top edge of this memand there is provided an thelateral.

her 8 is secured an elbow 9 to which the laterals are connected.' Thiselbow is provided with a stufiing box 10 in which is mounted a wrenchmember 11 which extends downwardly and the lower end isrecessed adaptedto engage the head of the bolt 3 for turning the bolt 3 and opening thevalve member 2, and to permit the flow of water out into It will benoted that the lower end of the bolt 3 is provided with a cotter pin 3to prevent the bolt 3 from being turned clear out of the nut 5.

Though I have shown and described a particular 7 construction,combination and arran ement of parts and portions I do not wisli to belimited to this particular construction, combination and arrangement norto the modification thereof but desire to include in the purview of myinvention the construction, combination and arrangement substantially asset forth in the appended claims. 7 V a f It is obvious that with thisconstruction there is provided a valve structure for irriation purposesin which the concrete plpe' orms. a support and seat for the valveformed bythevalve itself under pressure While the upper edge of the pipeis green thus providing a molded fit of the valve with the seat; thatthenut is supported in the bars embedded in the concrete forming asubstantial means for supporting the valve relatively to the seat; thatthe annular mem her 6 is supported against the ledge 1 which forms thesupport for the bolt 7 for securing the member 8 forming a tight jointbetween the'lateral elbowfand the top edge of the ledge 1 and asubstantial means for support ingtheelbow 9 relatively to the concretepiae 1. Y f r laving thus described myinvention what I claim as new anddesire to secure by Letters Patent, is:

1. A device of the class described including, a concrete pipe, a pair ofspaced apart lateral bars embedded-in the wall of said pipe andextending across the middle thereof some distance from the end, anintegral valve seat formed on the end of'said concrete plpe, a platewithitsouter edge conformingto said valve s-e'atprovided with a greenforming the seat by pressing the valve 7 against the end of saidpipe'and permitting the plastic material to set while in such position.

3. A device of the class described, including an annular plate providedwith a bifurcated flange extending from one side thereof near theedge,'a concrete pipe with anintegral valve seat on one end thereofconforming to and filling the space between said bifurcated flange andmeans embedded in said concrete pipe walls some distance from the endand connected with said plate for securing said plate rigidlyon saidintegral valve seat. g o v 4. A device of the class described including,an annular plate provided with a bifurcated flange extending from oneside thereof nearthe edge, a concrete pipe with its edge conforming tothe space between the parts of said bifurcated flange, means embedded insaid concrete and connected with said plate for securing said platerigidly on the edge of said concrete pipe, another flange on said pipe,an elbow provided witha bifur-- cated flange on one end engaging said131130,
